ini File Field Name
Web Parameter Name
Valid Range and Description
PreferRouteTable
[Prefer Routing Table]
Determines if the local Tel to IP routing table takes precedence over a
Proxy for routing calls.
0 = Only Proxy is used to route calls (default).
1 = The gateway checks the 'Destination IP Address' field in the 'Tel to IP
Routing' table for a match with the outgoing call. Only if a match is not
found, a Proxy is used.
Applicable only if Proxy is not always used
(‘AlwaysSendToProxy’ = 0, ‘SendInviteToProxy’ = 0).
EnableProxyKeepAlive
[Enable Proxy Keep Alive]
0 = Disable (default).
1 = Enable Keep alive with Proxy using OPTIONS.
2 = Enable Keep alive with Proxy using REGISTER.
If EnableProxyKeepAlive = 1, SIP OPTIONS message is sent every
ProxyKeepAliveTime. If EnableProxyKeepAlive = 2, SIP REGISTER
message is sent every RegistrationTime. Any response from the Proxy,
either success (200 OK) or failure (4xx response) is considered as if the
Proxy is correctly communicating.
This parameter must be set to 1 (OPTIONS) when Proxy
redundancy is used.
When EnableProxyKeepAlive = 2 (REGISTER), the homing
redundancy mode is disabled.
ProxyKeepAliveTime
[Proxy Keep Alive Time]
Defines the Proxy keep-alive time interval (in seconds) between Keep-Alive
messages.
The default value is 60 seconds.
This parameter is applicable only if EnableProxyKeepAlive = 1
(OPTIONS). When EnableProxyKeepAlive = 2 (REGISTER),
the time interval between Keep-Alive messages is determined
by the parameter RegistrationTime.
UseSIPTgrp
[Use Tgrp Information]
0 = Tgrp parameter isn’t used (default).
1 = (send only) The trunk group number is added as the ‘tgrp’ parameter to
the Contact header of outgoing SIP messages. If a trunk group number is
not associated with the call, the ‘tgrp’ parameter isn’t included. If a ‘tgrp’
value is specified in incoming messages, it is ignored.
2 = (send and receive) The functionality of outgoing SIP messages is
identical to the functionality described in option (1). In addition, for incoming
SIP messages, if the Request-URI includes a ‘tgrp’ parameter, the gateway
routes the call according to that value (if possible). If the Contact header
includes a ‘tgrp’ parameter, it is copied to the corresponding outgoing
messages in that dialog.
UserAgentDisplayInfo
[User-Agent Information]
Defines the string that is used in the SIP request header ‘User-Agent’ and
SIP response header ‘Server’. If not configured, the default string ‘3Com
product-name s/w-version’ is used (e.g., User-Agent: 3Com-Sip-Gateway-
V7122/v.4.80.004.008). When configured, the string ‘UserAgentDisplayInfo
s/w-version’ is used (e.g., User-Agent: MyNewOEM/v.4.80.004.008). Note
that the version number can't be modified.
The maximum string length is 50 characters.
